TECHNICAL FIELD

The present disclosure relates to a method and an apparatus for downloading and installing a communication service to and in a terminal in a communication system for a communication connection. More particularly, the present disclosure relates to a method and an apparatus for downloading and installing a profile in real time in a communication system.

BACKGROUND

To meet a demand for radio data traffic that is on an increasing trend since commercialization of a fourth generation (4G) communication system, efforts to develop an improved fifth generation (5G) communication system or a pre-5G communication system have been conducted. For this reason, the 5G communication system or the pre-5G communication system is called a communication system beyond 4G network or a system since the post long term evolution (LTE). To achieve a high data transmission rate, the 5G communication system is considered to be implemented in a super high frequency (mmWave) band (for example, like 60 GHz band). To relieve a path loss of a radio wave and increase a transfer distance of a radio wave in the super high frequency band, in the 5G communication system, beamforming, massive multiple input and multiple output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, and large scale antenna technologies have been discussed. Further, to improve a network of the system, in the 5G communication system, technologies such as evolved small cell, advanced small cell, cloud radio access network (cloud RAN), ultra-dense network, device to device communication (D2D), wireless backhaul, moving network, cooperative communication, coordinated multi-points (CoMP), and interference cancellation have been developed. In addition to this, in the 5G system, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC) that are an advanced coding modulation (ACM) scheme and a filter bank multi carrier (FBMC), a non-orthogonal multiple access (NOMA), and a sparse code multiple access (SCMA) which are an advanced access technology, and so on have been developed.

Meanwhile, the internet has evolved to an internet of things (IoT) network that transmits and receives information, such as things, between distributed components and processes the information, in a human-centered connection network through which a human being generates and consumes information. The internet of everything (IoE) technology in which the big data processing technology, etc., by connection with a cloud server, etc., is combined with the IoT technology has also emerged. To implement the IoT, technology elements, such as a sensing technology, wired and wireless communication and network infrastructure, a service interface technology, and a security technology, have been required. Recently, technologies such as a sensor network, machine to machine (M2M), and machine type communication (MTC) for connecting between things has been researched. In the IoT environment, an intelligent internet technology (IT) service that creates a new value in human life by collecting and analyzing data generated in the connected things may be provided. The IoT may be applied to fields, such as a smart home, a smart building, a smart city, a smart car or a connected car, a smart grid, health care, smart appliances, and an advanced healthcare service by fusing and combining the existing information technology (IT) with various industries.

Therefore, various tries to apply the 5G communication system to the IoT network have been conducted. For example, the 5G communication technologies such as the technologies of the sensor network, the machine to machine (M2M), the machine type communication (MTC) are implemented by techniques such as the beam-forming, the MIMO, the array antenna, or the like. An example of the application of the cloud radio access network (cloud RAN) as the big data processing technology described above may also be the fusing of the 5G technology with the IoT technology.

A universal integrated circuit card (UICC) is a smart card inserted into a mobile communication terminal, etc., and is called a UICC card. The UICC may include an access control module for accessing a network of a mobile carrier. An example of the access control module may include a universal subscriber identity module (USIM), a subscriber identity module (SIM), an internet protocol (IP) multimedia service identity module (ISIM), etc. The UICC including the USIM is generally called an USIM card. Similarly, the UICC including an SIM module is generally called an SIM card. In the following description of the present disclosure, the SIM card is used as a general meaning including the UICC, etc. in which the UICC card, the USIM card, and the ISIM are included. That is, the technology of the SIM card may be identically applied to the USIM card, the ISIM card, or even the general UICC card.

The SIM card may store personal information on a mobile communication subscriber and perform subscriber authentication and a generation of a traffic security key upon an access to a mobile communication network, thereby implementing the use of the safe mobile communication.

The SIM card is generally manufactured as a dedicated card for the corresponding mobile carrier by a request of a specific mobile carrier upon manufacturing of a card at this time of the filing of the present disclosure. A card in which authentication information for accessing a network, for example, universal subscriber identity module (USIM) application and international mobile subscriber identity (IMSI), a K value, an object linking and embedding (OLE) for process control (OPc) value or OPc value, etc., is mounted in advance is released. Therefore, the corresponding mobile carrier receives the manufactured SIM card and delivers the SIM card to a subscriber. Thereafter, if necessary, the SIM card may use technologies of over the air (OTA), etc., to perform managements of installation, modification, deletion, etc., of applications within the UICC. A subscriber inserts the UICC card into his/her own mobile communication terminal to use a network of the corresponding mobile carrier and application services. In addition, when replacing a terminal, a subscriber takes out the UICC card from the existing terminal and inserts the UICC card into a new terminal, such that the new terminal may use authentication information, a mobile communication telephone number, a personal telephone directory, etc., which are stored in the UICC as they are.

However, the SIM card is generally inconvenient for a mobile communication terminal user in receiving services of other mobile carriers. There could be an inconvenience in that the mobile communication terminal user needs to physically get the SIM card to receive services from a mobile carrier. For example, an inconvenience may occur when a mobile communication terminal user travels to other countries, and he or she needs to get an on-site SIM card to receive on-site mobile communication services. A roaming service may somewhat solve the foregoing inconveniences, but there is a problem in that the mobile communication terminal user may not wish to receive the roaming services due to an expensive fee and when a contract between providers are not established.

Meanwhile, a significant portion of the foregoing inconveniences may be solved by remotely downloading and installing the SIM module to and in the UICC card. That is, the SIM module of the mobile communication service to be used may be downloaded to the UICC card at the user's desired time. The UICC card may also download and install a plurality of SIM modules and may select and use only one of the plurality of SIM modules. The UICC card may be fixed in a terminal or may not be fixed in the terminal. In particular, the UICC fixed in the terminal is called an embedded UICC (eUICC). Generally, the eUICC fixed in the terminal means the UICC card which may download and select SIM modules remotely. According to various embodiments of present disclosure, the UICC card which may download and select the SIM module remotely is commonly called the eUICC. The UICC card fixed in the terminal or not fixed in the terminal among the UICC cards which may download and select the SIM modules remotely is commonly called the eUICC. Further, information on the downloaded SIM module is commonly used as the term eUICC profile.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

In connection with the above-mentioned embodiment, an embodiment of the present disclosure provides a method for downloading a profile to eUICC of an auxiliary terminal using a main terminal and a method for downloading a profile from a single terminal to eUICC.

FIG. 1 is a diagram illustrating a mobile communication connection method of a terminal using a UICC in which a profile fixed in the terminal is installed according to an embodiment of the present disclosure.

Referring to FIG. 1, a UICC 120 may be inserted into a terminal 110. In this case, the UICC may be a detachable type and may also be embedded in the terminal in advance. A fixed profile of the UICC in which the fixed profile is installed means that ‘access information’ which may access a specific provider is fixed. The access information may be a so-called international mobile subscriber identity (IMSI) which is a subscriber discriminator and a K value or a Ki value which is required to authenticate a network along with the subscriber discriminator.

Then, the terminal may use the UICC to perform the authentication along with an authentication processing system (so-called home location register (HLR) or authentication center (AuC) of a mobile carrier. The authentication process may be an authentication and key agreement (AKA) process. If the authentication succeeds, the terminal may use a mobile communication network or mobile carrier network 130 of the mobile communication system to use mobile communication services such as a telephone or a use of mobile data.

FIGS. 2A and 2B are diagrams illustrating a procedure of downloading and installing a profile using a 0^(th) profile access key according to an embodiment of the present disclosure.

The system of FIGS. 2A and 2B may include a provider server 205, a profile server 210, and a terminal 220. Further, the system may further include a user 215 and the user 215 may be an electronic device that receives an input from a user. The provider server 205 may be mobile network operator (MNO) and in the present disclosure, may be named a provider, a mobile carrier, a mobile carrier server, or the like. The profile server 210 may include a profile generation server and a profile providing server. The profile generation server and the profile providing server may be configured of one entity and may also be configured of independent entity. The profile generation server may be an SIM manufacturer server and may be named eUICC manufacture (EUM), an SIM manufacturer, or the like. The profile providing server may be named SM-DP, SM-DP+, or the like. The terminal 220 may include UICC. The UICC may be embedded in the terminal 220 and may also be inserted into the terminal 220. An UICC related operation may be performed in a local profile assistant (LPA) of the terminal 220. The LPA may also be named UICC application.

According to an embodiment of the present disclosure, to identify the 0^(th) profile access key, the 0^(th) profile access key value may be generated using a ‘0’ value. The profile access key may also be named the activation code. For example, if a value of a code version field of the activation code is 0, it may be appreciated that the profile access key is the 0^(th) profile access key. The term ‘0^(th) profile access key’ is only a term for differentiating other profile access keys and therefore the name of the access key that performs the same function and / or purpose is not limited thereto. The terminal 220 may transfer the 0^(th) profile access key to the profile server 210 to obtain the first profile access token.

An example of the procedure of downloading and installing a profile using the 0^(th) profile access key and the first profile access token will be described below with reference to FIGS. 2A and 2B.

The embodiment of FIGS. 2A and 2B may be divided into a profile preparation phase and a profile downloading phase. The two phases are not necessarily divided into an independent operation. The profile preparation phase is a procedure of preparing an output file and a profile access key between the provider server 205 and the profile server 210 to download the profile. The phase of downloading a profile is a procedure of downloading, by a terminal, a profile through the process of authenticating and verifying, by the provider server 205, the profile server 210, and the terminal 220, the profile download according to the request of the terminal

Profile Preparation Phase

In operation 231, the provider server 205 may order the profile server 210 to generate the profile. The provider server 205 may order the generation of a plurality of profiles. The operation may be made between the provider and the SIM manufacturer. The provider may transmit an input file including a list of IMSI values or band information to the SIM manufacturer (EUM) to order the SIM manufacturer to generate the plurality of profiles. The process may be named profile ordering.

In operation 233, the profile server 210 may generate an output file. The profile server 210 may generate the output file on the basis of the ordering of the profile generation. The operation 233 may be performed in the SIM manufacturer or the SIM manufacturer server. The output file may include IMSI, ICCID, and Ki values. The SIM manufacturer may generate the information including the IMSI, ICCID, and Ki values for each profile and provide the generated information to the operation.

In operation 235, the profile server 210 may generate the 0^(th) profile access key. The SIM manufacturer may generate N ^(0th) profile access keys. The profile access key may have a text form and may also generate text information as image information in a quick response (QR) code form. The 0^(th) profile access key may be named the activation voucher. The generated text information or the image having the QR code form and the information thereon may also be called the activation voucher.

An example of the ^(0th) profile access key may be as follows.

Example of 0^(th) profile access key: 0$TEST.DP.COM$0123456789ABCDEFGHIJ

That is, it may consist of identifiers ‘0’ and ‘$’ differentiating the 0^(th) profile access key, an address of an SM-DP+ server to be accessed, ‘$’, and the access token value of the 0^(th) profile access keys.

In the above example, “TEST.DP.COM” is an address of a server and “0123456789ABCDEFGHIJ” is the access token value. The ‘$’ differentiating information may be replaced by other characters or signs.

In operation 237, the profile server 210 may provide the information on the output file and the profile access key (or activation voucher) to the provider server 205. For example, the SIM manufacturer provides the generated output file and N 0^(th) profile access key to a provider. In this case, the 0^(th) profile access key may have a form in which it is printed on paper. The operations 231 to 237 need to be performed prior to generating any one of N profiles.

Profile Download Phase

In operation 241, the provider server 205 may receive a subscription request. The provider may receive the subscription request which may be a subscription request from the user 215. The subscription may also be performed offline at a carrier agent and may also be performed online at a carrier web portal. The subscription request from the user 215 may be a subscription request received from an electronic device that the user 215 uses and may also be a subscription request from an operation operated by a carrier agent according to an intention expression of the user 215.

In operation 243, a provider may provide one of the 0^(th) profile access keys received in the operation 237 to the user 215. The 0^(th) profile access key may be provided in the form in which it is printed on paper and may also be provided through E-mail or a web portal.

In operation 251, the terminal 220 may acquire the 0^(th) profile access key.
